A company being formed after reorganization at The Star-Ledger is taking space at 1 Harmon Plaza, the Secaucus office building where The Jersey Journal relocated to in January.

Penn Jersey Advance Inc. has signed a lease for 22,000 square feet, or the entire ninth floor, of the office property in the Meadowlands. It is one of the first tenant commitments that the building’s new owners, Woodland Park-based Mountain Development Corp. and PCCP LLC, have received since buying the property for $11.5 million in February.

Cushman & Wakefield Inc. is the leasing agent for 1 Harmon Plaza, and it brokered the lease with Penn Jersey as well as with a second new tenant, FolioDynamix. That wealth-management technology company will be relocating from Manhattan, and has taken 10,500 square feet on the sixth floor of the Secaucus property.

Penn Jersey Advance, which has a seven-year lease, will take occupancy of 1 Harmon Plaza next month, said Mountain Development President Michael Seeve.

The Jersey Journal moved to 1 Harmon Plaza in January, taking nearly 10,000 square feet on the top floor of the 10-story Secaucus office building. The daily newspaper left its nearly 90-year-old headquarters in Jersey City.

The Jersey Journal and The Star-Ledger are both owned by Advance Publications Inc., which announced a corporate reorganization on March 27. The newspaper publisher said that it was forming a company that would launch in September, Penn Jersey Advance Media Central Services. In online want-ads for positions such as financing planning and analysis manager, Penn Jersey Advance Central Services listed Secaucus as the location of the work.

The firm also described itself as “a shared-services company providing support services such as circulation, information systems and technology, finance and accounting support to NJ Advance Media, NJ.com, The Star-Ledger, The Times of Trenton, South Jersey Media Group, Lehigh Valley Media Group and NJN Publishing. The company will also provide HR support to all affiliates with the exception of The Star-Ledger.”

Star-Ledger Publisher Richard Vezza and Richard Diamond, president of Penn Jersey Advance, couldn’t be reached for comment Thursday.

In July Vezza announced that the Ledger had sold its long-time headquarters in Newark for an undisclosed sum to Maddd Equities, a real estate firm in Floral Park, N.Y. The daily newspaper had been at that site at 1 Star-Ledger Plaza, at the corner of Court and Washington streets, since 1966.

Penn Jersey was represented by the brokerage firm Douglas Elliman, which declined to comment, for the 1 Harmon Plaza lease. FolioDynamix was represented by CBRE Group Inc. Neither could be reached for comment.

One Harmon Plaza, which has 192,000 square feet, has a mirrored-glass fa├žade and fronts on the Hackensack River.
